Abstract
The invention discloses a brake system of a vehicle, which comprises a power conversion part, a hydraulic control assembly and a brake part. The brake system of the vehicle is characterized that the power conversion part comprises a flange plate and a clutch for combining with an oil pump or separating the flange plate or from the oil pump; a swinging motor is driven by the oil pump via the hydraulic control assembly; and a brake shoe is driven by the swinging motor. According to the invention, the traditional technical scheme of braking through complete wheel lock is greatly improved and sideslip and drift of the vehicle caused by wheel lock are avoided. The braking shoe is driven to swing through soft hydraulic energy so that the braking shoe generates friction with the ground for braking; and the braking force of the braking shoe touching the ground in a slow swinging process is gradually increased to be well adapted to the speed of the vehicle so that the harmful trend of sideslipcaused by high speed and forced brake is effectively reduced.
